Code
Error content
WRN SUB UNIT
W10*
Warning in the secondary unit with the P/S connection established
WRN PROCESS
W11*
Internal communication error => If this persists, the process shifts
to the FAIL process.
WRN SETTING
W12*
The number of connected Units does not match the setting during
P/S operation.
When setting P/S, the P/S Cable is not connected or the
connection is reversed.
When setting P/S, output control mode is constant voltage control.
WRN SELECT
W13*
When USER control is used, improper control mode selection for
USER1 PORT.
WRN LEVEL
W14*
When USER control is used, the command value of USER1 PORT
is out of specification range.
WRN FAN
W15*
If the cooling FAN failure persists, the process shifts to the FAIL
process.
WRN INPUT
W16*
If the input failure persists, the process shifts to the FAIL process.
WRN IN DROP
W17*
Input Voltage Lower Limit Out of Spec
WRN IN OVER
W18*
Input Voltage Upper Limit Out of Spec
WRN OUTPUT
W19*
If the output failure persists, the process shifts to the FAIL process.
WRN SHORT
W20*
Load short-circuited
WRN OVER VOLT
W21*
Output overvoltage
WRN OVER CUR
W22*
Output overcurrent
The * in ERROR is the unit No. Refer to [Table 4-13: ERROR code correspondence table during P/S
operation].
In the event of a warning, the DC output stops for a certain period of time.
If the symptom is improved, the output resumes even when the reset process is not performed.
